Title: Improvements in mechanical time fuzes for projectiles
IPC: F42C9/04
Filed: 1926-11-16
Abstract: 284,186. Junghans, O. Nov. 16, 1926. Projectile juzes.-Relates to clockwork time fuzes driven by centrifugal force and provided with one or more auxiliary clockworks for releasing safety devices, such as are described in Specification 285,553, and consists in so arranging the centrifugal driving weights that they can be disconnected from the clockwork after a testing operation and returned to the original position. In the form shown, the main clockwork, and an auxiliary clockwork are mounted between plates 2 - - 6 inserted in the fuze body 1 above a safety centrifugal shutter and detonating charge carrier a. The main clockwork, which is shown developed, comprises a gear train 10 - - 21, driven by a pair of pivoted toothed segments 7 carrying diametrically opposed centrifugal weights, and driving a balance 22 controlled by a spring blade 24 regulated by sliding blocks 23, which can be adjusted by means of screws 25. For testing purposes, the plate 6 is replaced by a plate 56, Fig. 4, formed with a recess 57 above the pinion 10. The clockwork is then spun in a machine at the same speed as the speed of rotation of the projectile, to regulate the balance. After this regulation, the pinions- 10, 11 are pulled up by their spindle 9 to disengage the pinion 11 from the pinion 12; the centrifugal weights 7 can then be turned back freely to their starting position, and re-engaged by moving the spindle 9 in again. The pinion 10 and the ends of the spindle 9 moving in its bearings are made long enough to allow of this up and down movement of the spindle; and the recess 57 in the plate 56 allows for the movement of the pinion 10.

Abstract: 391,836. Automatic exchange systems. POLLAK, J. E., 20, Holborn, London.- (Siemens & Halske Akt.-Ges.; Wernerwerk, Siemensstadt, Berlin.) Nov. 5, 1931, No. 30728. [Class 40 (iv).] In a system employing finder-switches, should a call be initiated when all the finders of the group are in use, the subscriber receives a busy signal and must re-initiate the call before it can be 'extended, even though a finder may become free in the meantime. When the subscriber Tl initiates a call, line relay R(I) energizes and closes a circuit through cut-off relay T (inoperative) and its own holding R (II) for start relay An which completes the driving circuit for the first idle finder AS. On the calling line being reached, test relay P energizes in series with cut-off relay T and relay R(I) and extends the starting circuit. If on the other hand all the finders are in use, start relay An completes a chain circuit for relay K, which short-circuits relay An. Relay T now energizes on account of the reduction of resistance and causes the relapse of relay R by disconnecting both its windings, whereupon a holding circuit over the loop is closed for relay T, which being slow to release holds up meanwhile. Busy tone is sent back from transformer 21. The subscriber Tl may be called at this time since no busy marking is applied.

Abstract: 229,272. Compagnie de Bethune. Feb. 11, 1924, [Convention date]. Ammonium sulphate. -In the conversion of ethyl sulphuric acid into alcohol by circulating it against steam and ammonia gas in a distillation column, the proportion of ammonia is so regulated that the ammonium sulphate produced remains dissolved in the diluted acid and is recovered in subsequent neutralization of the acid. Specifications 147,360, [Class 55 (ii), Gas manufacture &c.], and 197,315 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) describes also the use of the apparatus shown in the Figure (Cancelled), and refers to the production of ether. The lower part of a heat-insulated column a is filled with divided material on to which the ethyl sulphuric acid is run from a pipe b. Water vapour entering by the pipe f comes into contact with the descending acid and the resulting vapours are rectified in the upper part of the column a which constitutes a dephlegmator. The water condensed out returns to the lower part of the column, whilst the alcohol and ether vapours are drawn off from the top of the column or by the side pipes e to a condenser d. The side pipes e permit of the collection of a liquid of determined concentration in alcohol and ether. Ammonia gas is introduced into the apparatus by the pipe g to fix the residual acid as ammonium sulphate and to assist both in decomposing the ethyl sulphuric acid and in providing the heat required for the distillation of the product. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the manufacture of neutronabsorbing materials
Inventor: MCMILLAN PETER WILLIAM
IPC: G21F1/06
Filed: 1959-09-17
Abstract: A refractory glass-ceramic material capable of absorbing slow neutrons is made by forming a glass containing as a major constituent an oxide having a neutron capture cross-section greater than 5 X 1024 barns per gram of oxide at a point within the neutron energy range from 2.0 to 0 electron volts, shaping the glass, and devitrifying it by heating at a temperature just below that at which the glass will deform.  A silicate glass containing by weight 30-60% CdO, small amounts of In2O3, TiO2, Al2O3, Na2O, CaF2, BaF2, CdF2, and the remainder SiO2, is heated at the upper annealing temperature, for example 625-630 DEG  C., for at least half an hour, the temperature raised slowly, for example to 900 DEG  C., and maintained at this point for a similar time. Devitrification may be facilitate by including gold as a nuclearing agent.  A borate glass containing by weight 20-65% CdO, small amounts of In2O3, K2O, TiO2, BaF2, and the remainder B2O3, is similarly treated, although in this case heating at the upper annealing temperature is optional.  According to the Provisional Specification, the product may be used for nuclear reactor control rods or shielding material and may be clad with heat-resisting steel.
